Coughlin et al. (A-9) examined the breast and cervical screening practices of Hispanic and non- Hispanic women in counties that approximate the U.S. southern border region. The study used data from the Behavioral Risk Factor Surveillance System surveys of adults age 18 years or older conducted in 1999 and 2000.
